Next step is to pad stitch the heck out of it. The stitches go through all the layers. This part is easiest to do if working with the bodice laying flat. I worked with it laying on a fabric cutting board while standing. You do not want to pad stitch the straps as they need to stay soft to hug the shoulders when worn. Before stiching. Mark the seam allowance and the area to be pad stitched. You do not want to stich in the seam allowance. It’s easy to get lost in stitching and do too much.
